BM521Q25F
AC/DC controller IC for LED lighting Included 650V MOSFET

BM521Q25F is an AC/DC converter for LED lighting, which has a built-in MOSFET with 650V withstand voltage. This IC can be applied to quasi-resonant typed High-side LED driver application, and the high current precision and Low EMI noise can be achieved. Moreover, owing to the built-in PFC (Power Factor Correction) converter, the harmonics is improved. Owing to the start-up circuit with 650V withstand voltage, the low power consumption is achieved. And owing to the external current setting resistance, a power supply design with a high degree of freedom can be achieved. Owing to the built-in start-up circuit and MOSFET with 650V withstand voltage, a compact application can be designed easily, and the low-cost can be achieved with the small BOM size.
